A receive magazine for collecting and transporting sheets of exposed photographic media. The receive magazine includes an elongated, light-tight enclosure having front and back walls, top and bottom walls, and first and second end walls. Sheets of media are gravity fed into the magazine entrance through a collection door on the top wall of the enclosure. The collection door includes a media-receiving slot, a shutter and a spring for biasing the shutter to a normally closed, light-tight position over the slot. A lower downwardly sloping resilient member mounted to the front wall engages the sheets as they are inserted into the magazine and forces the sheets into a vertically stacked arrangement against the back wall of the enclosure, away from the entrance. A ramp surface on the back wall guides sheets being inserted over previously collected sheets. A compound curved surface on the back wall of the enclosure below the ramp surface arcs the sheets to minimize contact during insertion. Collected sheets of media can be removed from the magazine through a retrieve door on the front wall.

Improved lubricator roll for uniformly applying low viscosity lubricant to surfaces such as fusing rolls used in copying or reproduction machines. The roll has a longitudinal array of apertures for dispensing low viscosity lubricant contained in the roll and a longitudinal, interior strip which scoops lubricant into an annular reservoir formed between the strip and the roll. The annular reservoir provides a head on the lubricant near the dispensing apertures so that lubricant is dispensed therefrom over approximately three-fourths of each revolution, regardless of the level of lubricant in the roll. The reservoir-forming strip also modulates the amount of lubricant present in the reservoir so that the roll apertures alternately dispense oil and vent the roll.
